Various embodiments of the present invention provide methods for designing multilayer nanowire crossbars that are functionally equivalent to two-layer nanowire-crossbar designs. Given a two-layer nanowire-crossbar design having two or more columns of microregions, in certain embodiments, the method conceptually folds the two-layer nanowire crossbar between columns of microregions. The folded nanowires, located in the conceptually folded, two-layer nanowire-crossbar design, are collapsed into shorter length nanowires to give a multilayer nanowire-crossbar design that includes the same number of nanowire junctions as in the two-layer nanowire-crossbar design.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A method for obtaining a multilayer nanowire-crossbar design that is functionally equivalent to a two-layer nanowire crossbars design, the method comprising: receiving the two-layer nanowire-crossbar design having two or more microregions; folding the two-layer nanowire-crossbar design between the two or more microregions; and collapsing folded nanowires into single nanowires, which yields the multilayer nanowire-crossbar design.
2. The method of claim 1 wherein folding the two-layer nanowire-crossbar design between microregions further includes bending horizontal nanowires.
3. The method of claim 2 wherein the bent horizontal nanowires have straight parallel nanowire segments.
4. The method of claim 1 wherein folding the two-layer nanowire-crossbar design between the two or more microregions further includes positioning microregions opposite and parallel to one another.
5. The method of claim 4 wherein positioning microregions opposite and parallel to one another further includes positioning vertical nanowires within oppositely and parallel microregions opposite and parallel to one another.
6. The method of claim 1 wherein collapsing the folded nanowires into shorter nanowires further includes retaining nanowire junctions connecting vertical nanowires and horizontal nanowires.
7. A computer instruction encoded in a computer readable medium for obtaining a multilayer nanowire-crossbar design that is functionally equivalent to a two-layer nanowire crossbars design, the computer instruction comprising: logic that receives a first data set corresponding to the two-layer nanowire-crossbar design having two or more microregions; logic that folds the two-layer nanowire-crossbar design between the two or more microregions; and logic that collapses folded nanowires into single nanowires, which yields a second data set corresponding to the multilayer nanowire-crossbar design.
8. The computer instruction of claim 7 wherein logic that folds the two-layer nanowire-crossbar design between microregions further includes bending horizontal nanowires.
9. The computer instruction of claim 8 wherein the bent horizontal nanowires have straight parallel nanowire segments.
10. The computer instruction of claim 7 wherein logic that folds the two-layer nanowire-crossbar design between the two or more microregions further includes positioning microregions opposite and parallel to one another.
11. The computer instruction of claim 10 wherein positioning microregions opposite and parallel to one another further includes positioning vertical nanowires within oppositely and parallel microregions opposite and parallel to one another.
12. The computer instruction of claim 7 wherein logic that collapses the folded nanowires into shorter nanowires further includes retaining nanowire junctions connecting vertical nanowires and horizontal nanowires.
13. A system for obtaining a multilayer nanowire crossbar design that is functionally equivalent to a two-layer nanowire crossbars design, the system comprising: a computer processor; a communications medium by which a first data set corresponding to the two-layer nanowire-crossbar design having two or more microregions is received; and a program, stored in one or more memory components and executed by the computer processor that folds the two-layer nanowire-crossbar design between the two or more microregions, and collapses the folded nanowires into single nanowires, which yields a second data set corresponding to the multilayer nanowire-crossbar design.
14. The system of claim 13 wherein folds the two-layer nanowire-crossbar design between microregions further includes bending horizontal nanowires.
15. The system of claim 14 wherein the bent horizontal nanowires have straight parallel nanowire segments.
16. The system of claim 13 wherein folds the two-layer nanowire-crossbar design between the two or more microregions further includes positioning microregions opposite and parallel to one another.
17. The system of claim 16 wherein positioning microregions opposite and parallel to one another further includes positioning vertical nanowires within oppositely and parallel microregions opposite and parallel to one another.
18. The system of claim 13 wherein collapses the folded nanowires into shorter nanowires further includes retaining nanowire junctions connecting vertical nanowires and horizontal nanowires.
